They had returned to the little garden-gate by this time. Clement Austin stretched out his hand.

"Good night, Miss Wilmot."

"Good night."

Margaret opened the gate and went into the garden. Mr. Austin walked slowly homewards, past pleasant cottages nestling in suburban gardens, and pretentious villas, with campanello towers and gothic porches. The lighted windows shone out upon the darkness. Here and there he heard the sound of a piano, or a girlish voice stealing softly out upon the cool night air.

The sight of pleasant homes made the cashier think very mournfully of the girl he had just left.

"Poor, desolate girl," he thought, "poor, lonely, orphan girl!" But he thought still more about that which he had heard of Henry Dunbar; and the evidence against the rich man seemed to grow in importance as he reflected upon it. It was not one thing, but many things, that hinted at the guilt of the millionaire.

The secret possessed, and no doubt traded upon, by Joseph Wilmot; Mr. Dunbar's agitation in the cathedral; his determined refusal to see the murdered man's daughter; his attempt to bribe her—these were strong points: and by the time Clement Austin reached home, he—like Margaret Wilmot, and like Arthur Lovell—suspected the millionaire. So now there were three people who believed Mr. Dunbar to be the murderer of his old servant.

CHAPTER XIX.
LAURA DUNBAR'S DISAPPOINTMENT.

Arthur Lovell went often to Maudesley Abbey. Henry Dunbar welcomed him freely, and the young man had not the power to resist temptation. He went to his doom as the foolish moth flies to the candle. He went, he saw Laura Dunbar, and spent hour after hour in her society: for his presence was always agreeable to the impetuous girl. To her he seemed, indeed, that which he had promised to be, a brother—kind, devoted, affectionate: but no more. He was endeared to Laura by the memory of a happy childhood. She was grateful to him, and she loved him: but only as she would have loved him had he been indeed her brother. Whatever deeper feeling lay beneath the playful gaiety of her manner had yet to be awakened.

So, day after day, the young man bowed down before the goddess of his life, and was happy—ah, fatally happy!—in her society. He forgot everything except the beautiful face that smiled on him. He forgot even those dark doubts which he had felt as to the secret of the Winchester murder.
